β¦ Synopsis
Graphite crystals with thickness ranging from about 100 to 1500 ,A and were prepared b) cleavage. From measurement of the magnetoresistance and the Hall coefficient the electronic properties were determined by the McClui-e's method. The total carrier density does not change much with thickness. with n,. exceeding IL,,, while pLr, ph and p,,/~~ decreases with decreasing thickness.
EPR between 4~2Β°K and 300Β°K of a carbon black family: P33

The thermal expansion of the interlayer spacmg bnd the intensity ratio ~(004)/1(00?) of the diffraction lines of graphite-bromine residue compounds were measured at temperature5 between room temperature and 700Β°C by using a high temperature X-ray diffractometer. At about 330Β°C. both the c-spacing a
## Abstract The kinetics of bromination of several aromatic compounds (anilides, anisoles, and phenols) was investigated in 80% aqueous acetic acid (v/v) in the temperature range 20β50Β°C using __N__βbromosuccinimide (NBS) as the reagent. The reaction was found to be first order in the aromatic subs
